In this work, five manganese(II) complexes derived from chelidamic acid were designed, synthesized, and evaluated as bleaching catalysts for the activation of hydrogen peroxide under mild and aqueous conditions. The ligand framework was functionalized by O-alkylation at the 4-hydroxy group with neutral, cationic, and anionic substituents to modulate hydrophobicity and charge distribution. All complexes were tested in morin bleaching as a benchmark reaction, exhibiting good conversions (&amp;gt;90%) already at 20 \u00b0C within a short reaction time (30 min). The O-functionalized Mn(II) complexes significantly outperformed the free hydroxyl analogue and Mn(II) salt precursor. Kinetic analysis revealed the presence of an induction period, followed by a quasi-linear regime used to determine apparent turnover frequencies (TOF), ranging from \u223c80 to 180 h\u20131. The catalytic behavior was strongly influenced by the reaction medium, showing a marked dependence on bicarbonate buffer concentration, achieving optimal activity at moderate alkaline pH (\u22489.3). Notably, efficient bleaching was achieved at low catalyst concentrations (\u03bcM range) and low hydrogen peroxide loadings (0.05% w\/w). Furthermore, the catalytic system was also effective in the oxidation of the azo dye Sunset Yellow FCF, supporting its potential application in the wastewater treatment of degradation-resistant pollutants. These results highlight the importance of ligand design in tuning catalytic performance and support the potential application of these manganese complexes as sustainable bleaching catalysts operating under mild conditions.<\/jats:p>","DOI":"10.1021\/acsomega.6c04886","type":"journal-article","created":{"date-parts":[[2026,8,7]],"date-time":"2026-08-07T21:01:36Z","timestamp":1786136496000},"page":"48483-48496","source":"Crossref","is-referenced-by-count":0,"title":["Boosting Peroxide\nReactivity: New Mn(II) Chelidamate\nCatalysts for Efficient Low-Temperature Bleaching"],"prefix":"10.1021","volume":"11","author":[{"given":"Immacolata","family":"Manco","sequence":"first","affiliation":[{"name":"Universita\u0300 di Napoli Federico II , , Via Cintia 21 , ,","place":["Napoli, Italy, 80126"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9068-3092","authenticated-orcid":true,"given":"Vincenzo","family":"Langellotti","sequence":"additional","affiliation":[{"name":"Universita\u0300 di Napoli Federico II , , Via Cintia 21 , ,","place":["Napoli, Italy, 80126"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4964-1047","authenticated-orcid":true,"given":"Maria E.","family":"Cucciolito","sequence":"additional","affiliation":[{"name":"Universita\u0300 di Napoli Federico II , , Via Cintia 21 , ,","place":["Napoli, Italy, 80126"]},{"name":"Consorzio Interuniversitario di Reattivita\u0300 Chimica e Catalisi , Via Celso Ulpiani 27 , ,","place":["Bari, Italy, 70126"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlo","family":"De Luca","sequence":"additional","affiliation":[{"name":"Universita\u0300 di Napoli Federico II , , Via Cintia 21 , ,","place":["Napoli, Italy, 80126"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2063-9050","authenticated-orcid":true,"given":"Roberto","family":"Esposito","sequence":"additional","affiliation":[{"name":"Universita\u0300 di Napoli Federico II , , Via Cintia 21 , ,","place":["Napoli, Italy, 80126"]},{"name":"Consorzio Interuniversitario di Reattivita\u0300 Chimica e Catalisi , Via Celso Ulpiani 27 , ,","place":["Bari, Italy, 70126"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matteo","family":"Lega","sequence":"additional","affiliation":[{"name":"Impresa Fater SpA , Via Mare Adriatico 122 , ,","place":["Spoltore, Italia, 65010"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5842-7600","authenticated-orcid":true,"given":"Massimo","family":"Melchiorre","sequence":"additional","affiliation":[{"name":"Consorzio Interuniversitario di Reattivita\u0300 Chimica e Catalisi , Via Celso Ulpiani 27 , ,","place":["Bari, Italy, 70126"]},{"name":"ISusChem Srl , Piazza Carita\u0300 32 , ,","place":["Napoli, Italy, 80134"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9169-3452","authenticated-orcid":true,"given":"Gabriella","family":"Pinto","sequence":"additional","affiliation":[{"name":"Universita\u0300 di Napoli Federico II , , Via Cintia 21 , ,","place":["Napoli, Italy, 80126"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5952-523X","authenticated-orcid":true,"given":"Oreste","family":"Tarallo","sequence":"additional","affiliation":[{"name":"Universita\u0300 di Napoli Federico II , , Via Cintia 21 , ,","place":["Napoli, Italy, 80126"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1624-079X","authenticated-orcid":true,"given":"Francesco","family":"Ruffo","sequence":"additional","affiliation":[{"name":"Universita\u0300 di Napoli Federico II , , Via Cintia 21 , ,","place":["Napoli, Italy, 80126"]},{"name":"Consorzio Interuniversitario di Reattivita\u0300 Chimica e Catalisi , Via Celso Ulpiani 27 , ,","place":["Bari, Italy, 70126"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,8,7]]},"reference":[{"issue":"3","key":"2026081811080459000_cit1","doi-asserted-by":"publisher","first-page":"203","DOI":"10.1515\/tsd-2023-2575","article-title":"The Impact\nof Detergent Performance on Sustainable Consumer Laundry Behavior:\nA Socio-Technical Challenge","volume":"61","author":"Cortez","year":"2024","journal-title":"Tenside, Surfactants,\nDeterg."},{"issue":"4","key":"2026081811080459000_cit2","doi-asserted-by":"publisher","first-page":"1729","DOI":"10.1021\/acssuschemeng.4c09073","article-title":"Laundry Bleaching:\nEvaluating the Environmental Benefits of Automatic Dosing Systems\nwith Electrochemical Reactors","volume":"13","author":"Enstrup","year":"2025","journal-title":"ACS Sustainable\nChem.
